He became a prolific author of short fiction, and novels — not just science fiction, but also horror, Westerns, mysteries, and juvenile fiction — from 1946 until his death in 2006. The film The Last Days on Mars (an adaptation of “The Animators”) and the Tales of the Darkside episode “The Circus” are based on stories by him. In 2005, two collections of his fiction were released under the title The Best of Sydney J. Bounds: Strange Portrait and Other Stories, and The Wayward Ship and other Stories.
